Archie McPhee Spy Pen Invisible Ink and Blacklight

Product Description

Pretend you're an international super spy on an undercover operation to save the Earth from an evil maniac with plans to take over the world with a solar-powered satellite laser gun. What is the one accessory you'd need most? The Spy Pen, of course! Mata Hari never had it so good and James Bond wishes Q would finally get one for him.

Each 5" plastic spy pen features ink that is made of special high-brightness compounds that are invisible to the naked eye, but magically illuminate when exposed to a blacklight. Conveniently located on the opposite end of the pen, the blacklight allows you to read any messages left to you by your spy friends. Perfect for writing down secret spy messages, scrawling secret grocery lists or keeping a catalogue of all of your internet passwords. You can leave undetectable messages on just about any surface - keyboard keys, monitor frames, desks, walls, tables and pieces of paper, of course. Without the light of the spy pen, no one will ever know they're there. Battery included.
